Features: This is a dc-dc buck converter module that converts 6.5V-60V to 1.25-30V, the maximum current is 10A. The converter module is used for step-down voltage so make sure the input voltage is higher than the output voltage. The buck module can be extremely efficient (up to 97%), making it useful for voltage reduction. The input and output are designed with screw terminals for convenient connection. Widely used for low voltage system power supply, 6V, 12V, 14V, 24V battery charging and power supply regulated Specifications: Input: 6.5V-60V Output: 1.25V-30V (adjustable) Efficiency: 97%(Max) Operating temperature: -40°C - +85°C Load capacity: 10A (max) Module Size: 7.1x2.2cm/2.8x0.87inch Quantity: 1 Pc Note: Please allow 1-3mm error due to manual measurement.
